public class FindMaxCountNumber {
	 public static void main(String args[]){  
		 	findMax("abcbccffccddiiiddaa"); 
	}
        public static void findMax(String str) {
		    	  int maxLength=0;
		    	  String maxStr="";
		    	  while(str.length()>0){
			    	  int length=str.length();
		    		  String first=str.substring(0,1);
		    		  str=str.replaceAll(first, "");
		    		  if(length-str.length()>maxLength){
		    			  maxLength=length-str.length();
		    			  maxStr=first;
		    		  }
		    	  }
	    		  System.out.println(maxLength);
